Introduction
This document describes the proposed solution for a universal input, 2.7 W LED ballast
with coupled inductor using the FL7701. The input voltage range is 90 VRMS – 265 VRMS
and there is one DC output with a constant current of 300 mA at 9 V. This document
contains a general description of FL7701, power supply specifications, schematic, bill of
materials, and typical operating characteristics.
1.1.
Description
The FL7701 LED lamp driver is a simple IC with a Power-Factor Correction (PFC)
function. The special “adopted digital” technique automatically detects the input voltage
condition and sends a special internal reference signal, resulting in the high power factor.
When AC input voltage is applied to the IC, the PFC function is automatically enabled.
When DC input voltage is applied to the IC, the PFC function is automatically disabled.
The FL7701 does not require a bulk capacitor (electrolytic capacitor) for supply-rail
stability, which can significantly affect LED reliability.

Notes:
1. The output current has ILEDPK ripple. To reduce ripple current, use a large electrolytic capacitor
in parallel with the LED. Ensure the capacitor voltage rating is high enough to withstand an
open-LED condition or use a Zener diode for protection.
2. The output power is not equal to the apparent power due to the slight phase shift between the
output voltage and current.

Typical Waveforms: Startup
Figure 10 through Figure 13 show the typical startup performance at different input
voltage conditions. When AC input voltage is applied to the system, the FL7701
automatically operates in AC Mode after finishing an internally fixed, seven-cycle, softstart period. Figure 12 and Figure 13 show the soft-start characteristics when a DC input
voltage is applied.

Operating Frequency & Minimum Duty
The programmable switching frequency is between 20 kHz and 250 kHz, determined by
selecting the RT resistor value. If no RT resistor is used (RT pin OPEN), the FL7701
default switching frequency is set to 45 kHz. The maximum duty ratio is fixed below
50% and has a fixed minimum typical on-time of 400 ns. There are two crucial points to
design properly. The first is consideration of the minimum duty ratio at minimum input
voltage because the FL7701 is limited to 50% duty ratio. The second consideration is
minimum on-time at maximum input voltage condition. The FL7701 cannot control
output power when the operating conditions are such that the required on-time is less than
the 400 ns minimum on-time.

1.98 µs

Operating Temperature
Figure 32 through Figure 39 show the steady-state thermal results with different input
voltage conditions. Inductor L3 has the highest temperature on the top side of the PCB
due to copper resistance. The FL7701 has the highest temperature on the bottom side of
the PCB due to power loss associated with the high-voltage device. The IC temperature is
74.7°C for the 220VAC input condition.

ANTI-COUNTERFEITING POLICY
Fairchild Semiconductor Corporation's Anti-Counterfeiting Policy. Fairchild's Anti-Counterfeiting Policy is also stated on our external website,
www.fairchildsemi.com, under Sales Support.
Counterfeiting of semiconductor parts is a growing problem in the industry. All manufacturers of semiconductor products are experiencing
counterfeiting of their parts. Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation,
substandard performance, failed applications, and increased cost of production and manufacturing delays. Fairchild is taking strong measures to
protect ourselves and our customers from the proliferation of counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts
either directly from Fairchild or from Authorized Fairchild Distributors who are listed by country on our web page cited above. Products customers buy
either from Fairchild directly or from Authorized Fairchild Distributors are genuine parts, have full traceability, meet Fairchild's quality standards for
handling and storage and provide access to Fairchild's full range of up-to-date technical and product information. Fairchild and our Authorized
Distributors will stand behind all warranties and will appropriately address any warranty issues that may arise. Fairchild will not provide any warranty
coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is committed to combat this global problem and encourage our
customers to do their part in stopping this practice by buying direct or from authorized distributors.
